MAINTENANCE

Bevel gear

The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

Lubricating the flexible drive shaft

Inside the hollow drive shaft of the edger is a flexible drive shaft. This flexible drive shaft should be regularly lubricated every 25 hours in operation. Loosen the two screws on the bevel gear and remove it. The flexible drive shaft is easily removed from the hollow shaft by taking a firm grip on the shaft end. Lubricate the entire length of the flexible drive shaft and reinsert it in the hollow drive shaft. Turn the shaft while inserting it so that it correctly engages in the clutch. Refit the bevel gear on the hollow drive shaft and tighten the two screws.

Adjusting the edger’s cutting depth

The cutting depth must be adjusted before starting work.

Loosen the locking knob (A) and rotate the guard by moving the locking knob forwards or backwards. If the locking knob is moved forwards (away from the machine) the cutting depth is increased. If the locking handle is moved backwards (towards the machine) the cutting depth is reduced.
